3 Claims.

This invention relates to computing machines, and more particularly tothe paper holding apparatus thereof.

This application is a division of my application Serial No. 248,431,filed December 30, 1938.

An object of this invention is to provide the paper carriage of suchmachines with a tally roll support that is simple in construction andwhich may be readily adjusted to accommodate varying widths of tallyrolls.

With this and incidental objects in view, the invention consists incertain novel features of construction and combinations of parts,theessential elements of which are set forth in appended claims, and apreferred-embodiment of which is hereinafter described with reference tothe drawing which accompany and form part of the specification.

In said drawing:

Figure 1 is a top plan view of a paper carriage showing the improvedpaper holding means, together with the customary roller platen,

Figure 2 is a front elevation thereof, showing also the customarypressure rolls for cooperating with the platen for feeding the paper,

Figure 3 is a right side elevation thereof, and

Figure l is a side elevation of details of the adjusting means for thepaper holding means.

The invention is illustrated as applied to a paper carriage of the typecommonly used on adding machines, although it is to be understood thatits use is not restricted to machines of this character.

The carriage is illustrated as having a base I and side members 2 and 3.A platen d is secured on a platen shaft 1 that is mounted for rotationin sides 2 and 3. A pair of paper feed rollers 13 are mounted in acradle Id located centrally between sides 2 and 3, and hold the 40 paperagainst the platen, under the tension of a spring 15 secured at one endto a pin it on the cradle and to a lug IT on the base i. Cradle M isloosely mounted upon a tie rod i8 secured between sides 2 and 3. A paperguide 26 for di- 45 recting the paper from the supply roll to the platenis mounted rearwardly of the platen.

A pair of laterally adjustable tally roll supports 30 are slidablymounted upon two rods 3i and 31 secured rearwardly of paper guide 25.Supports 50 30 are formed at their forward ends with projections 32which guide the paper as it passes from the tally roll to the platen.The sides of the supports serve as lateral guides for the tally paperduring the feeding thereof. The lower forward ends of projections 32terminate at a sufficient distance to the rear of the platen so thatforms such as deposit slips and the like, indicated at H3, may bereadily inserted at the rear of the platen.

Cylindrical studs 33 of a size to fit snugly within the tally roll coreare riveted to the inner sides of supports 3d for mounting the roll. Thesnug fit between the studs and the core provides sufficient friction topreclude superfluous unwinding of the paper as it is fed.

Annular grooves 35 are cut in rod 3! at spaced points corresponding tothe different widths of tally rolls to be used. Sleeves 34 are slottedon their upper and lower sides as at ts and 3!, re-

spectively, slots 46 being deeper than slots ii, and having their basesflush with the bases of grooves 39 in rod 3 l. U-shaped springs 42areinserted in the slots 4t and 4!, slot at preferably being peened orotherwise upset against the lower leg of the spring to hold the springin place, leaving the upper leg thereof free to flex and latch withingrooves 38. When changing from a tally roll of one width to one ofanother, the operator need only pull supports 3i! toward or away fromeach other, out of their latched engagement with one set of grooves andinto engagement with the other set, thus effecting a quick and easylateral adjustment.

While the form of mechanism herein shown and described is admirablyadapted to fulfill the objects primarily stated, it is to be understoodthat it is not intended to confine the invention to the one form ofembodiment herein disclosed, for it is susceptible of embodiment invarious forms all coming within the scope of the claims which follow.

What is claimed is:

1. A paper holding apparatus for computing machines including a framehaving upstanding side members, a rod extending from one side member tothe other, two supports for holding a paper roll, and being slidable onsaid rod to accommodate rolls of variable widths, spaced recesses insaid rod, and yielding means co-acting with said recesses to hold thesupports in their adjusted positions.

2. A paper holding apparatus for computing machines including a framehaving upstanding side members, two rods extending from one side memberto the other, two supports for holding a paper roll, and being slidableon said rods to accommodate rolls of variable widths, spaced recesses inone of said rods, and yielding means coacting with said recesses to holdthe supports in their adjusted positions.

3. A paper holding apparatus for computing machines including a framehaving upstanding side members, a rod extending from one side member tothe other, two supports slidable on the rod for holding paper rolls ofdifferent widths, recesses spaced on said rod to correspond to thedifferent widths, sleeves mounted on said supports and having slots, thebases of two of said slots being flush with the bases of the saidrecesses, and the bases of the other slots being outside the peripheryof said rod, and U-shaped springs inserted in the slots and having their5 legs bearing against the said bases.
